1 arguments were passed to a function which expects 3. Query step not working for if statement.

Hi,

We have got a solution where in one of the steps 'if' statement takes a current date and translates it to sprint number. It checks the current date versus what is in the code.
 
The erroneous step is built in the following way:

= if (DateTime.Date(DateTime.LocalNow())<=#date(2018,1,2)) then "Sprint from 2017" else
* lots of conditions for each sprint as the one below.
if (DateTime.Date(DateTime.LocalNow())>=#date("2018,12,19") and DateTime.Date(DateTime.LocalNow())<=#date("2019,1,1")) then "Sprint 51" 
else ""

Until recently, it worked like a charm. However, it does give us a following error message:
Expression.Error: 1 arguments were passed to a function which expects 3.
Details:
    Pattern=
    Arguments=List


Any ideas if Microsoft has changed recently that it these kind of statements do not work anymore? Any ideas how to correct such code to get it working?

Thanks!

Hi @przos,

The #date("2018,12,19")  should be #date(2018,12,19). The double quotes make the three parameters as one. Please check it and try again.

Best Regards,

Dale

Hi,

A while ago my PowerBI query stopped working.

One of our mechanism contains solution where new Custom column is being created. It takes current date and then displays Sprint Number (2 weeks range for a sprint). Until recently, this worked all right, but now I get a following message:

Expression.Error: 1 arguments were passed to a function which expects 3.
Details:
    Pattern=
    Arguments=List

The code:
= if (DateTime.Date(DateTime.LocalNow())<=#date(2018,1,2)) then "Sprint from 2017" else
*lots of ifs based like the one below here from S1 to S49

if (DateTime.Date(DateTime.LocalNow())>=#date("2018,12,19") and DateTime.Date(DateTime.LocalNow())<=#date("2019,1,1")) then "Sprint 51" 
else ""

Solution does not pick up the data through/from the gateway and gets it from OFeed. Until this step (Custom Column) all works well. Has Microsoft changed anything here recently?

Anyone could help me with defining what is wrong or how to correct it?
